Logos Global Management LP SCHEDULE 13G filed 2026-09-10

Logos Global Management LP, a Delaware entity with a business address at 1 Letterman Drive, Bldg C, Suite C3-350, San Francisco, CA, filed a Schedule 13G with the SEC on 2026-09-10 under accession number 0000935836-26-000483. A Schedule 13G is the form used to report a beneficial ownership position in a public company's equity. The record links this filing to Longeveron Inc., CIK 1721484, which trades on Nasdaq under the ticker LGVN, is incorporated in Delaware, is classified under SIC 2834, Pharmaceutical Preparations, is categorized as an emerging growth company, and lists a business address at 1951 NW 7th Avenue, Suite 520, Miami, FL, 33136. Longeveron was formerly named Longeveron LLC. The portion of the filing captured here is Exhibit 99.1, the joint filing agreement, not the cover pages that carry the position itself. In it, the signatories agree to file jointly any statements on Schedule 13D, Schedule 13G, or Forms 3, 4 and 5 required under Section 13(d) or 16(a) of the Securities Exchange Act of 1934, and they appoint Logos Global Management LP, a Delaware limited partnership, as their agent and attorney-in-fact to prepare, sign and file those documents. The agreement is dated September 10, 2026. For an analyst or a journalist, the useful detail in this excerpt is the shape of the filing group rather than the size of the stake. The signatories are Arsani William and Graham Walmsley as individuals, plus Logos Global Management LP, Logos Opportunities Fund V LP acting through Logos Opportunities Fund V GP LLC as its manager, Logos Global Management GP LLC, and Logos Opportunities V GP LLC. Arsani William signs for every entity, as Managing Partner of Logos Global Management LP and as Managing Member of the three LLCs. That tells you which funds and general partners are being treated as a single reporting group, and who controls them. The share count, the percentage of the class, the split between sole and shared voting and dispositive power, and the date of the event that triggered the filing are not in the excerpt available here. Neither is any statement of whether this is an initial Schedule 13G or an amendment to an earlier one.
